BALlNG-PRESS.

SPECIFICA'IIION forming part of Letters Patent No. 311,68, dated February 3, 1885.

Appliratii n tiled March 24, 1F84. (No model I 0,73 whom, it may concern:

Be it known that l, ALBERT S. ROBINSON, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Baling Presses, of which the following is aspecitication.

My invention relates to that class of balingpresses in which a sweep-lever is employed with mechanism for imparting to the platen a reciprocating movement; and it consists of the parts and devices and combinations and arrangements of devices,hereinafter fully described and set forth.

The objects of my invention are to provide means for guiding the compressed material from the pressing-chamber through the balingchamber to its exit without bending or buckling under the pressure of the platen; also, to provide a toothcd-gear-lever pressing mechanism which will be cheap in construction, simple in. its parts, efcient in operation, and not liable to get out of order, and be operated by the vibrating movement of a sweep-lever; also, to provide mechanism which will hold the sweep-lever from sagging or moving out of a horizontal plane; also. to provide elastic dogs for operating with pressed sections of material to hold the same from moving back, and, further, to provide a friction mechanism which will operate with the sweep-lever at the time of each` movement otl the same past its point of center of motion, for preventing a rebound oit' said lever when the platen has finished its full length of forward thrust against the material being compressed. I attain these objects by means of the devices and combinations ot' devices illustrated in the accompanying drawings, (in three sheets) forming a part of my specication, in which- Figure l represents a plan View of a balingpress embodying my improvements, two feet ot' baling-chamber,broken ont. Fig. 2 is a side elevation of the same. Fig. 3 is a hori Zontal sectional view, on an enlarged scalo, of a side (a section thereof, and showing a retaining-dog) ofthe press, taken at line l l in Fig. 4.. Fig. 4t is a cross sectional view through a side ot' the press at line 2 2 in Fig. 2, showing the retaining-dogs ou an enlarged scale. Fig. 5 is a plan View of the gear-lever mechanism for operating the platen on an enlarged scale. Fig. 6 is a rearend elevation of the press. Fig. 7 is a front end elevation of the press. Fig. 8 is a sectional elevation of 55 the friction or brake mechanism for preventing a rebound ofthe sweeplever,taken at line 3 3 in Fig. l and line 4. 4 in Fig. 2; and Fig.

9 is a sectional and detail View of the same, taken at line 5 5 in Fig. 8. 6o

All the above detail views are on an enlarged scale.

The same letters of reference` refer to sin1ilar parts throughout the several Views.

In the drawings, A A represent the bottom sills'of the press. A A are the top plates; A`-, the vertical side posts, and A3 the crossbars. These pieces are joined together, and are securely held together by bolts or in any proper manner, as practiced by the trade, and 7o together form the framework of the body of the press.

B is the platen chamber, in which platen I (shown by dotted lines in Fig. 2) is moved in a reciprocating manner, and C is the balingchamber. The plateirchamber has its vertical and top and bottom sides made close or substantially tight by side linings or boards, as is the practice hy the trade, andthe top and v bottom sides, act, of the chamber are continued 8o tothe balingchamber and extended to the rear end thereof, as shown by dotted lines in Fig. 2. The portion oftop lining, a, forming the top wall of the baling-chainber,ris unsupported and disconnected in its entire length from the rear end of the platen-chamber to the rear end of the baling-chamber, so as to be free to be deected toward bottom lining, a', by means of mechanism heretofore employed by myself and not forming a part ot' this inven- 9o tion. rIhe sills A A and plates A A are made with a greater extension in their vertical direction than in their horizontal direction, as shown in Fig. (i, and top lining, a, is so arranged in relation to plates A that the o5 lower surfaces of said top lining will be on a horizontal plane about two inches, more or less, above a line, y, drawn with the horizontal plane of the lower side of said top plates. (lllustratedinFig.6.) Bottomlining, rco

c', is arranged in such a relation to sills A that thc upper surface of said bottom lining will be on a horizontal plane about two inches, more or less, below a line, i5, drawn with the planes of the upper side surfaces of said sills, as shown in the same iigure. By these arrangements of the top and bottom linings, aa', with sills and plates A A', the portions ofthe inner and oppositely-located vertical sides, a'z a, of said sills and plates are made to project inward from the inner side surfaces of the respective linings, and form guides or ways by which the compressed material will be held from buckling in the heling-chambers, and be guided through the same to an exit at the rear end of the press, while at the same time a saving of material and cost of construction is effected.

Located at the end of the platen-chamber B, next to baling-chamber C, and in the side ,y of the-press, are a series of elastic retainingdogs, T T, which Work in openings au, made through the side timbers, A2, and linings of the press and supplemental bar A4. These dogs are shown in Figs. 3 and 4, and are each provided with a beveled head, t', which are arranged with their straight sides toward the baling-chamber and their bevel running back toward the platen-chamber. each made elastic by springs s, steadyingstems s2, and held against plate u2 and secured at the outer .side by a key, a', as shown, or a nut. Each vertical side of the baling-chamber is provided with a single opening. O, eX- tending horizontal from the rear end of the platenchamber to the rear end of the balingchamber, and in a vertical direction from theV lower side surface of top plate, A', to the upper side surface of sill A. Through these side openings, O O, a bale maybe bound with any desired number of bands `in an easy and convenient manner. D is the feed-'hopper communicating to the platen-chamber through opening b.

P is the platen. (Shown in dotted lines in Fig. 2.) E is an arm hinged to the rear side ofthe same,- and F F is a lever hinged to arm E, as shown in Figs. 1 and 2, and actuates said pitman in a reciprocating moving manner, accordingly as said lever is vibrated from its fulcrum d. This lever has its long arm Fand short arm F made, preferably, ot a single piece of cast metal, and short arm F is made in the form of a toothed section of an ellipse, as shown in Fig. --that is to say, the said arm is in the form of a section of an elliptical coggear, having teeth c, arranged on the face ot' the rim of the same, as shown.. The fulcrum of this lever consists of shaft d, supported in suitable bearings', e e, from the frame of t-he press. The arm F ot' this lever practically forms with arm E, hinged to the platen, a toggle-lever.

G G is the'sweep-lever, composed of wood and metal, and mounted on the vertical shaft f, .which is held in suitable bearings from the pressft'rame. The long arm G ot' the lever projects outward from its fulcrumfand forms the sweep-lever, to which the animal is These dogs arek l hitched for operating the pressing mechanism of the press. The short arm G of the sweeplever is made in the form of a section of an eccentric gear, having its cogs or teeth c corresponding with the cogs or teeth c ot' short arm F of thecoacting-lever F F. The fulcrumshaftf of the sweep-lever G G is so situated in relation to the toothed surface of short arm G' as to be nearer to the middle ofthe length of its toothed periphery, which is made on a curve ofa true circle, than the terminating ends thereof, as shown in Figs. l and 5. The form of construction ofthe short arms of these two coacting-levers F F and G G are peculiar in their relative curvatures of their re spective toothed portions. The curvature of arm F is that of a section of an ellipse with the fulcrum set at a point back from the center of the same to such a distance as .to be within the rear end portion of the curve if the ellipse were continued unbroken. The arm G of the sweep-lever is made in the form of a section ofa true circle with the fulcrum at a point eccentrically to the same and near the middle of the length ot the curve, and on a line with a line drawn longitudinally through lever g from one end to the other. 'With these forms of curvatures each halt' of the whole line ot' cogs on the elliptical "curve of arm F, from y to i will correspond in length with the length ot' the whole line of cogs on the true circle curve of arm G from x to x2. Made with these curves, as and with the fulcrum of each set ,as above described and shown, the teeth of each arm will fully and truly engage with those of the other in their entire length of respective lines. When sweep-lever G is moved in either direction from that shown by t'ull lines to that shown by dotted lines in Fig. 5, the cogged arm G will operate cogged arm F ot' lever lF and move it to a corresponding position shown by dotted lines in the same figure, and thereby operate with hinged arm E ot' platen P to draw it back, and when the sweep-lever G G is moved back to full lines the arms E and F will be operated substantially as a toggle-lever, with a gradually lessenin'g of speed .of forward movement of the platen and a gradually-increasing power.

I provide a brake mechanism which will op'- erate to retard the free movement ot` the same when the toggle-levers E and F are passing from coincident lines of position and the plat-- en is about to be drawn back, and until the platen has ceased to be iniiuenced by the reactive force ofthe material in the pressing and baling chambers ofthe press.

This mechanism consists of plate Q, Figs. 7, 8, and 9, having an elastic support at the lower side of bar H by means ot' upright arms ZZ, working in vertical ways 7c k, springs s s. perforated necks m m, and adjustable flanged nuts n n. This plate is prevented from shifting endwise by shouldersjj. This plate is Y provided at its horizontal sides with ways o-o,

ATo prevent the rebound of the sweep-lever,

IOO

Fig. 9, with which ways is arranged the traveling brake-roller R, having` its bearing in housing g, provided with flanges o o. These iianges of the housing of roller It iit loosely in ways 0 0 of plate Q, and being thus arranged, the said housing and roller will be adapt-ed to be moved in either` direction from one end of said plate to the other.

Secured to the upper side of sweep-lever G and beneath plate Q is tlat plate g, having its upper surface on a plane above the upper surface of said lever. hen the sweep-lever is moved from right to left.. the cud ot' plate g will strike roller It on its right-hand side and move it with its housing from position of full lines in Figs. 7 and 8 to position indicated by dotted lines in the same figures` when its further movement will be checked by left-hand side shoulder, j, and the lefthand end of plate g will then pass under roller R and bc pressed down on plate g (or sweeplever G) hy the force of springs s s, exerted through plate Q and the connected housing q, and this pressure will be continued until the sweep-lever has been carried to such a distance to theleft hand as to carry plate g wholly beneath the roller R and from beneath the same. rIhis pressure of roller R on the sweeplever when passing beneath the former will effectually check the rebound of the latter.

, IVhen sweep-lever is reversed, roller R will be carried from its position indicated by dotted lines to that shown by full lines, when the same operation of the parts will be had and the same results will be obtained.

Secured to the frame-work ofthe press are one upper and one lower circular ways, L L, between which sweeplever works. These circular ways are preferably made of pieces of timbers eut in sections of a circle and joined together, though they may be made ot'iron, or iron and wood combined. These ways are plated with circular wear-plates tt, and secured to the lower side of the sweep-lever is a short Wearplate, 1?, which has bearing on lower wear-plate, t, or lower ways, L. These ways support the outwardly-extended portion ofthe sweep-lever from dropping downA ward and hold the same in one horizontal plane throughout its entire length of movement.

By the above-described improvements I am enabled to produce an effective press, which will not be liable to get out of order and will have its sweep-lever prevented from rebounding and annoying the animal operating the sweep, while the bales produced thereby may be tied oft' with any desired number ot' balebands.
